To all whom z'wnay, concern."

Beit known tha-tl, F 1min FEEDERLm citizenl'ofv the Germ-an Republic,`residing at Obernd'orf-on-the-NeckanL Germany, 'ha-ve inventedvcertainnew and useful Improve-k ments in ;Magazine. Rifles'` of Small Caliber',of which the .following is: ay specification.Y

My invention relates to a magazinerifle ofasmall caliber andyprovidedwith al bolt breech Imechanism.

The'primary lobject'of myinvention is to provide awrile' oftheabove'indicated type that is extremely1 simpleI in construction, strong:and durable. 'and yhighly 'practical 'ins asmuch asdisturbances'or,accidents such as jamming.' ofthefcartridges-or the likeare reduced to a wminimum,`

Another object'fof my invention yis to yprovide improved means' forvafreadyv change of the magazine and for af high:y degree: of safety.Various other objects and/advantages will become apparent during. thecourse of the; following description.

These objects are accomplished by such means as arezshown'in theirpreferredfform in thewaccompanying drawings,A described in the followingspecification: and thereafter more specifically pointed out intheyappendedy claims In1the accompanying` drawingswherein like charactersdesignate like parts through-y out the'several views:

The frontk portion-of thebolt 1 is of an essentially smaller diam--` eter than the rear portionthereof, two longitudinal parallel recesses 2 and 8 being cut in thewall of said front portion with their inner-endssloping into the outerface of the bolt. Intermediate the two `recesses 2 and 3 aI ridge lisformed at the bottom side of the bolt, saidridge being adapted toprojectbetween the lateral lips 5 of the magazine 6,'- when the bolt isyin its Vretracted oropen position, as will be Clearly understood froman inspection of Figures 9 and 10. It will be seen; that the lips 5 ofthe magazine 6 engage in the recesses 2 and 3,r so that the upper rim ofthe magazine and the uppermost cartridge therein lie in the closestpossible proximity to the' axis ofthe barrel. lnthis manner a means `isprovided forreadily and properlyintroducing the cartridge into thecartridge chamber offthe barrel.

The casing or sleeve 7, Figures (Sand '7,' in which the' bolt'y 1 isguided duringV its -re'- ciprocal movements for reloading the-rifle, isclosed at the top. and has, as usual, in thev forward end of its`right'hand wall an openin-g 8`for the ejectionof the spent cartridgeshells anda longitudinal slot 9 terminating in an 1 enlarged rectangularopening. 10 :for loc-king; purposes. handle 11 of the bolt'assumes ahorizontal position, as shownin dotted linesliniF'igure 10,- a-nd.insuch positionvthefl handle is in alignment with thee slot 19,'soth'atthe breech canbe opened vin the usual mannerby with; drawing'theboltL by means'of thehand'le: Then locked, however, the handle 11assumes thedepending position shown in Fig-k ure 2,A engaging in therectangular' opening; 10.-v Owingto this construction ofthe'casingi orsleeve 7 with an uninterrupted plane upper face any suitable means forthe attach ment of a field glass or other appropriate sighting devicemay be readily applied thereto, if a field glass is affixed at the topof the sleeve the opening and closing of the bolt will not be obstructedthereby.

The portion 14 of the bolt is provided with a longitudinal lug or rib15, as will be seen in Figures 2 and 8, extending over the whole lengththereof. Then the breech is closed the said lug 15 engages in the slot 9of the sleeve to the full of its length, but even when the breech isopened the lug still remains in engagement thereinto a certain extent,so that the portion 14 and the firing mechanism located therein areprevented from being rotated. Y

The magazine 6 of the rifle has the rear bottom corner shaped to form anincline 16, Figure 11, adapted to co-operate with a correspondinglyinclined face of the pivotally mounted magazine holder 17, Figures 1 and9. rl`his construction permits the magazine to be removed from the rifleby simply drawing or pressing the same backwards towards the holder 17since the latter then recedes so that the co-acting faces disengageandthe magazine will be free to drop out of its housing. f

The holder 17 is provided with a spring acting' in such a manner thatthe lips 5 of the magazine, when the breech is opened, will be forced toengage in the recesses 2 and 3 of the bolt, whereas when the breech isclosed, that is to say, when the bolt 1 is caused to advance from itsposition shown in Figure 9 towards the left-hand side, the magazine willbe free to escape downwards, as soon as the rear sloping ends of therecesses 2 and 3 pass over the aid lips 5 and the latter come in contactwith the unrecessed smooth face of the forward portion of the bolt.`When the parts under consideration assume this position the bolt can beturned so that the handle 11 will be brought into locking engagementwith the forward wall of the opening 10, Figure 7, in order to adopt theposition shown in Figure 2, irrespective of the recesses 2 and 3 whichcannot interfere. At the operation of opening the breech the magazine isautomatically lifted by the spring-actuated holder 17 into its upperposition with the lateral lips engaging in the recesses 2 and 3 of thebolt.

The lips 5 of the magazine are so constructed as will be seen in Figure12, that the mouth formed between them decreases in width towards theirforward ends. The result thereof is that, particularly if rimlirecartridges are employed, the uppermost cartridge, in ascending into thesleeve or casing 7, Figure 9, assumes a gradually more and more inclinedposition with respect to the cartridge chambercf the barrel, since therim of the cartridge, in moving forwards between the two lips 5, islowered more and more owing to the decreasing width of the mouth. Inthis way a high degree of reliability is ensured in driving theuppermostcartridge into the chamber of the barrel and the danger ofjamming is reduced to a minimum.

Obviously, if rim-fire-cartridges are employed the lower cartridges inthe magazine necessarily must lie in a more declined position than anyupper ones. In order to avoid any undesired play or clearance whichwould Vresult in. causing the cartridge rims to not lie properlysuper-posed one over the other, the magazine is given a tapered shape,that isto say, it is, as regards its width, smaller at the bottom thanat the top, as will be clearly seen from Figure 11. In order that therims of the cartridges in the magazine may lie in `front of each other,the magazine is given a par icularly inclined position in the rifle.

The carrier 18 of the magazine is shaped to form a shallow cavity 19,which is of a depth increasing freni left to right in Figure 13. Theridge 2O formed at the right-hand end serves the purpose of holding therims Vof the superposed cartridges, at least Vin the lowerpart of themagazine, a little distance apart from the end wall thereof, yso that,friction between the cartridge and the magazine wall vwill be avoided.Owing to this `fact a relatively light spring V21 may be employedwhereby the operation of refilling the magazine with cartridges will befacilitated. y

As will be seen in Figure 11 the carrier 18 is pivotally connected withthe spring 21, preferably by bending the upper end of the spring inwardsto form the pivot, so that the position of the cartridge carrier 18 willautomatically be accommodated to the variations in the direction orrelative positions of the lowermost cartridge in the magazine. Thedirection of the inclined bottom of the magazine corresponds orisadjusted to the position of the lowermost cartridge in the filledmagazine.

The safety device for locking the trigger and the bolt in their cockedposition is shown in Figures 14 to 19.V The device comprises a slide 22having a knurled thumbpiece. The said slide is mounted on the left sideof the rifle adjacent to the scar 23 of the trigger-mechanism andadapted to be shifted lengtlnvise. .as shown in Figures 14; and aspring-eontrolled locking pin is provided in connection with the slide22 and the pin is adapted to engage in one or the other of two notchesprovided in the sleeve, just as the device is put safe or not.

The slide 22 has a longitudinal slot in engagement with a stationary pinand is provided at its fore end with a projection or tooth "24 adaptedto rest upon the lSear 23, when-the slide is set sa'fej and to therebylock the said sea'r and the trigger, as -will be seen in Figures 15 and16. Then the parts have assumed the described positions a nose 25projecting from the slide 22 upwards in close vproximity to theprojection 24, engages in a recess 26 in the bolt so that the latterlikewise will be locked by the slide. The slide is mounted and locatedin the rifle in such a manner that any pressure imparted to the triggereither accidentally or on purpose cannot cause the trigger or the boltto be released, when the slide is set safe or in locked position.

A further safety arrangement provided in the rifle consists in a meansby which the trigger, if the bolt is not fully locked, will be iiXed andunable tov be moved. To this end the bolt is provided with anotherrecess or groove 33, Figures 3 and 16, adapted to receive a nose 34integral with the sear 23 when, and only when, the breech is duly lockedas shown in Figure 16. In all cases, however, where the bolt is notcorrectly locked the nose 34 is in contact, or approximately so, Withthe peripheral face of the bolt, so that the sear and consequently thetrigger cannot be actuated. It will be seen that ring is impossibleunless the bolt is completely locked.

Mounted in the bolt is the firing pin 27 having a spring 28 coiled aboutits rear end to hold the pin normally in a retracted position, as shownin Figure 1. The front end of the spring 28 rests on the bottom of thebore in which the springy is housed, while its rear end is in contactwith a disk 29 rigid With the pin and abutting against a nose 30 of theextractor 31 as shown in Figure 1. The spring 28 is more powerful thanthe spring coiled about the Hring rod 32 so that, after the firingimpact, the spring 28 acts to force back the rod 32, against the actionof the spring` coiled thereabout, until the disk 29 again is in contactwith the nose 30 of the extractor and the pin 27 reassumes its normalposition, as in Figure 1.

It is apparent that in carrying my invention into effect some changesfrom the construction and arrangements herein shown and described may bemade. I Wish it therefore to be understood, that I do not limit myselfthereto, but hold myself at liberty to make such departures therefrom asmay fairly fall within the spirit and scope of my invention.
